I don't completely understand it myself. I have a Focal system with k3s installed and about 70 pods (about 150 containers) and about 70 veth devices.
In /lib/systemd/system/systemd-networkd.socket under "[Socket]" I have set "ReceiveBuffer=128M". Maybe that "128M" isn't enough but I can't add any more pods without getting "Could not enumerate addresses: No buffer space available" errors, so I *assumed* there's more to that patch than just the ReceiveBuffer setting. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1912331 Title: Many interfaces lead to "kernel receive buffer overrun" Status in systemd: Fix Released Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Focal: Won't Fix Status in systemd source package in Groovy: Fix Released Bug description: This is about a systemd-networkd bug, described here: https://github.com/systemd/systemd/issues/14417 There's a patch available: https://github.com/systemd/systemd/pull/16982 Can this be backported to Focal?
